Product Description:

The HCS03.1E-W0350-A-05-NNBN is a drive controller produced by Bosch Rexroth Indramat for the HCS IndraDrive Controllers series. Installed inside electrical cabinets, it converts fixed-frequency plant power into controlled DC-bus and pulse-width-modulated outputs for motor axes. The unit acts as the central regulating element in modular IndraDrive systems, executing speed, torque, and positioning commands issued by higher-level PLCs. Because the control and power sections are integrated in one housing, the drive can respond quickly to changing load conditions and motion commands. This layout also supports compact cabinet installations where coordinated axis control is required.

The controller accepts a supply of 3 x AC 400...500 V +10%, -15%, so it can be wired directly to standard three-phase networks without an isolation transformer. Within this input window, its power stage is rated for 15 to 75 kW, which suits medium-size machinery such as packaging lines and material-handling stations. Cabinet ingress protection is limited to IP20, so the unit must be mounted in a closed control panel. Heat is removed by internal air cooling delivered through an integrated blower, which avoids the need for external ducting. The DC link supports infeeding and feeding operation, allowing regenerative energy to return to the mains during deceleration.

The unit is design version 1, placing it in the first revision of this product family. Its HCS03 identifier marks the mechanical footprint and heat-sink capacity used for the 35 A current class in the series. Parameter libraries are matched to voltage code 05, confirming compatibility with the designated mains category and supporting proper setup within that voltage range. It is classified as an HCS Drive Controller, so it accepts standard IndraDrive axis interface cards, encoder modules, and safety options without modification. This makes it suitable for modular systems that rely on common accessories across multiple axes.
